A Randomized Controlled Clinical Study on the Application of the Third Space in the Operation of Gastric Submucosal Tumor

In the researchers' words

Gastric submucosal tumors (SMTs) are rare findings during routine upper endoscopy; the incidence of these lesions may be as high as 0.4%.SMTs display a wide spectrum,ranging from benign to highly malignant, with gastrointestinal stromal tumors (GISTs) being the most common type.SMTs is a gastrointestinal tumor,surgical operation is still the main method of gastric tumor treatment.The common surgical methods for resection of SMTs include laparotomy and laparoscopic surgery.In recent years, the Da Vinci robot assisted gastric resection has become a new way to treat gastric cancer. Compared with the traditional laparoscopy and laparotomy, the operation of the robot is more precise and flexible, with obvious advantages of minimally invasive and good application value and prospect.In recent years, some scholars have put forward the concept of the third space.The concept of the "third space" was initiatively proposed at the same time when new endoscopic surgery approach via natural orifice transluminal was put forward(NOTES). To be specific, with respect to the first space(lumen) and second space(peritoneal cavity),the third space refers to the intramural space.The aim of the study is to compare value (outcomes/costs) of surgery in patients with SMTs by 2 approaches:Laparoscopic and Endoscopic cooperative surgery(LECS),Robotic and Endoscopic cooperative surgery(RECS).First of all,…
